Stainless steel ball valve is a common instrument of valve, first used for block, distribution, and change the movement direction of the medium, has simple structure, small volume, light weight, small fluid resistance, convenient maintenance, etc. Stainless steel ball valve in use requirements must cherish, to ensure the normal operation of stainless steel ball valve. Stainless steel ball valve how to cherish? Small make up today is to introduce detailed measures for the protection of stainless steel ball valve. Measures for the protection of stainless steel ball valve: top: blank finished product in the future, pickling, must be washed clean, if have sand holes may be punched website production costs, should cherish welding with argon arc welding of its gas. Solid fusion processing and grinding, then; The second: the finished product, processing completion of pressure test in the future. Should use to rust powder water for flushing. Third: in the process of transportation to use wooden cases as far as possible, do not contact with metal products. Fourth: pipeline installation in the future, to cherish and maintenance on time, such as the stem out often with lubricating oil. Appropriate open and closed valve a few times. Make the ball, stem, sealing surface inclusions. Stainless steel ball valve as well as reducing and reducing channel is usually two kinds of structure. Regardless of the structure, the flow resistance coefficient of ball valve is small. Especially is the so-called full flow type, namely not reducing ball valve, due to its channel diameter equal to the inner diameter pipe, part of the resistance loss as long as the conflict of equal length of pipe resistance, namely in all valves, the ball valve minimum flow resistance. In the rocket and its experimental system, the request of transporting pipeline resistance as small as possible. To reduce the resistance of the pipeline system has two paths: one is to land the fluid velocity, therefore demand pipe diameter and valve size, about the efficiency of pipeline system often produce whammy effect, particularly for low temperature transporting system ( Liquid hydrogen) Is a very unlucky. ( 1) Part of the valve reduce the resistance and thus, a ball valve have naturally become the best selection. ( 2) Ball valve open/close switch, convenient quickly. As usual because the ball valve in case need to handle rolling fully open or close the 90 ° is finished, simply complete the quick opening and closing. Can complete agile open-close henan personnel test network, some structure of opening and closing time is only 0. 05 ~ 0. 1 s to ensure that can be used for the active system test bench. Quick opening and closing valves, no impact on the operation. ( 3) Ball valve sealing performance is good. The vast majority of ball Industrial Valves seat is made of elastic materials such as the teflon, sealing pair of metal and nonmetal materials, called soft seal as usual. As usual, soft sealing simple ensure sealing, and the sealing surface of machining accuracy and surface roughness request is not high. ( 4) Ball valve use long life. Because ptfe have excellent self-lubrication, less wear of conflict with the sphere, and because the ball processing technology improvement, landed the roughness, and then advances the use of the ball valve life.
